Frequently Asked Questions About Solar Panels in Bunbeg
How much do solar panels cost in Bunbeg?
A 4kWp system in Bunbeg typically costs €5,000-€8,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €3,200-€6,200. The system generates approximately 3,268 kWh/year, paying for itself in 4-6 years.
Do solar panels work in winter in Donegal?
Yes, solar panels generate electricity all year round. While output is lower in winter, Donegal still receives usable daylight hours even in December. Annual generation figures (3,268 kWh for a 4kWp system) already account for seasonal variation.
What is a BER assessment and do I need one?
A Building Energy Rating (BER) assessment is required after installing solar panels to claim the SEAI grant. A BER assessor visits your home and rates its energy efficiency from A1 to G. Solar panels typically improve your BER by 1-2 grades. The assessment costs around €150-€200.
How does shading affect solar panels in Bunbeg?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
Can I get solar panels on an east or west facing roof in Bunbeg?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
What happens to my solar panels if I move house in Bunbeg?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. The SEAI grant does not need to be repaid if you sell. Your installer can transfer monitoring accounts to the new owner.
Is my roof suitable for solar panels in Bunbeg?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
